[7.x] ILM: don't take snapshot of a data stream's write index (#58159) (#58222)
We don't allow converting a data stream's writeable index into a searchable
snapshot. We are currently preventing swapping a data stream's write index
with the restored index.

This adds another step that will not proceed with the searchable snapshot action
until the managed index is not the write index of a data stream anymore.

MappedFieldType should not extend FieldType (#58160)
MappedFieldType is a combination of two concerns:

* an extension of lucene's FieldType, defining how a field should be indexed
* a set of query factory methods, defining how a field should be searched

We want to break these two concerns apart. This commit is a first step to doing this, breaking
the inheritance relationship between MappedFieldType and FieldType. MappedFieldType
instead has a series of boolean flags defining whether or not the field is searchable or
aggregatable, and FieldMapper has a separate FieldType passed to its constructor defining
how indexing should be done.

Add JNA license to SQL CLI dependency licenses
Previously we excluded requiring licenses for dependencies with the
group name org.elasticsearch under the assumption that these use the
top-level Elasticsearch license. This is not always correct, for
example, for the org.elasticsearch:jna dependency as this is merely a
wrapper around the upstream JNA project, and that is the license that we
should be including. A recent change modified this check from using the
group name to checking only if the dependency is a project
dependency. This exposed the use of JNA in SQL CLI to this check, but
the license for it was not added. This commit addresses this by adding
the license.

[7.x][ML] Add categorizer stats ML result type (#58001)
This type of result will store stats about how well categorization
is performing.  When per-partition categorization is in use, separate
documents will be written for every partition so that it is possible
to see if categorization is working well for some partitions but not
others.

This PR is a minimal implementation to allow the C++ side changes to
be made.  More Java side changes related to per-partition
categorization will be in followup PRs.  However, even in the long
term I do not see a major benefit in introducing dedicated APIs for
querying categorizer stats.  Like forecast request stats the
categorizer stats can be read directly from the job's results alias.

Adds support for reading in `model_size_info` objects.

These objects contain numeric values indicating the model definition size and complexity.

Additionally, these objects are not stored or serialized to any other node. They are to be used for calculating and storing model metadata. They are much smaller on heap than the true model definition and should help prevent the analytics process from using too much memory.

[7.x] Ensure Joni warning are logged at debug (#57302) (#57897)
When Joni, the regex engine that powers grok emits a warning it
does so by default to System.err. System.err logs are all bucketed
together in the server log at WARN level. When Joni emits a warning,
it can be extremely verbose, logging a message for each execution
again that pattern. For ingest node that means for every document
that is run that through Grok. Fortunately, Joni provides a call
back hook to push these warnings to a custom location.

This commit implements Joni's callback hook to push the Joni warning
to the Elasticsearch server logger (logger.org.elasticsearch.ingest.common.GrokProcessor)
at debug level. Generally these warning indicate a possible issue with
the regular expression and upon creation of the Grok processor will
do a "test run" of the expression and log the result (if any) at WARN 
level. This WARN level log should only occur on pipeline creation which 
is a much lower frequency then every document. 

Additionally, the documentation is updated with instructions for how
to set the logger to debug level.

Deprecte Rounding#round (#57845) (#57893)
This deprecates `Rounding#round` and `Rounding#nextRoundingValue` in
favor of calling
```
Rounding.Prepared prepared = rounding.prepare(min, max);
...
prepared.round(val)

```

because it is always going to be faster to prepare once. There
are going to be some cases where we won't know what to prepare *for*
and in those cases you can call `prepareForUnknown` and stil be faster
than calling the deprecated method over and over and over again.

Ultimately, this is important because it doesn't look like there is an
easy way to cache `Rounding.Prepared` or any of its precursors like
`LocalTimeOffset.Lookup`. Instead, we can just build it at most once per
request.

[7.x] DataStream creation validation allows for prefixed indices (#57750) (#57799)
We want to validate the DataStreams on creation to make sure the future backing
indices would not clash with existing indices in the system (so we can
always rollover the data stream).
This changes the validation logic to allow for a DataStream to be created
with a backing index that has a prefix (eg. `shrink-foo-000001`) even if the
former backing index (`foo-000001`) exists in the system.
The new validation logic will look for potential index conflicts with indices
in the system that have the counter in the name greater than the data stream's
generation.

This ensures that the `DataStream`'s future rollovers are safe because for a
`DataStream` `foo` of generation 4, we will look for standalone indices in the
form of `foo-%06d` with the counter greater than 4 (ie. validation will fail if
`foo-000006` exists in the system), but will also allow replacing a
backing index with an index named by prefixing the backing index it replaces.

[ML] inference performance optimizations and refactor (#57674) (#57753)
This is a major refactor of the underlying inference logic.

The main refactor is now we are separating the model configuration and
the inference interfaces.

This has the following benefits:
 - we can store extra things with the model that are not
   necessary for inference (i.e. treenode split information gain)
 - we can optimize inference separate from model serialization and storage.
 - The user is oblivious to the optimizations (other than seeing the benefits).

A major part of this commit is removing all inference related methods from the
trained model configurations (ensemble, tree, etc.) and moving them to a new class.

This new class satisfies a new interface that is ONLY for inference.

The optimizations applied currently are:
- feature maps are flattened once
- feature extraction only happens once at the highest level
  (improves inference + feature importance through put)
- Only storing what we need for inference + feature importance on heap

[7.x] Ensure type exists for all monitoring configuration (#57399) (#57704)
#47711 and #47246 helped to validate that monitoring settings are
rejected at time of setting the monitoring settings. Else an invalid
monitoring setting can find it's way into the cluster state and result
in an exception thrown [1] on the cluster state application (there by
causing significant issues). Some additional monitoring settings have
been identified that can result in invalid cluster state that also
result in exceptions thrown on cluster state application.

All settings require a type of either http or local to be
applicable. When a setting is changed, the exporters are automatically
updated with the new settings. However, if the old or new settings lack
of a type setting an exception will be thrown (since exporters are
always of type 'http' or 'local'). Arguably we shouldn't blindly create
and destroy new exporters on each monitoring setting update, but the
lifecycle of the exporters is abit out the scope this PR is trying to
address.

This commit introduces a similar methodology to check for validity as
#47711 and #47246 but this time for ALL (including non-http) settings.
Monitoring settings are not useful unless there an exporter with a type
defined. The type is used as dependent setting, such that it must
exist to set the value. This ensures that when any monitoring settings
changes that they can only get added to cluster state if the type
exists. If the type exists (and the other validations pass) then the
exporters will get re-built and the cluster state remains valid.

Tests have been included to ensure that all dynamic monitoring settings
have the type as dependent settings.

Instead of force stopping the job, it would make more sense to
try to stop the job gracefully first. So we now try that out first.
If normal stop fails, then we resort to force stopping the job to
ensure we can go through with the delete.

In addition, this commit introduces `timeout` for the delete action
and makes use of it in the child requests.

[7.x] Ensure default watches are updated for rolling upgrades. (#57185) (#57563)
For a rolling/mixed cluster upgrade (add new version to existing cluster
then shutdown old instances), the watches that ship by default
with monitoring may not get properly updated to the new version.
Monitoring watches can only get published if the internal state is
marked as dirty. If a node is not master, will also get marked as
clean (e.g. not dirty).

For a mixed cluster upgrade, it is possible for the new node to be
added, not as master, the internal state gets marked as clean so
that no more attempts can be made to publish the watches. This
happens on all new nodes. Once the old nodes are de-commissioned
one of the new version nodes in the cluster gets promoted to master.
However, that new master node (with out intervention like restarting
the node or removing/adding exporters) will never attempt to re-publish
since the internal state was already marked as clean.

This commit adds a cluster state listener to mark the resource dirty
when a node is promoted to master. This will allow the new resource
to be published without any intervention.

Restore xpack.ilm.enabled and xpack.slm.enabled settings (#57383)
In #55592 and #55416, we deprecated the settings for enabling and disabling
basic license features and turned those settings into no-ops. Since doing so,
we've had feedback that this change may not give users enough time to cleanly
switch from non-ILM index management tools to ILM. If two index managers
operate simultaneously, results could be strange and difficult to
reconstruct. We don't know of any cases where SLM will cause a problem, but we
are restoring that setting as well, to be on the safe side.

This PR is not a strict commit reversion. First, we are keeping the new
xpack.watcher.use_ilm_index_management setting, introduced when
xpack.ilm.enabled was made a no-op, so that users can begin migrating to using
it. Second, the SLM setting was modified in the same commit as a group of other
settings, so I have taken just the changes relating to SLM.

[7.x] ILM: add support for rolling over data streams (#57295) (#57515)
As the datastream information is stored in the `ClusterState.Metadata` we exposed
the `Metadata` to the `AsyncWaitStep#evaluateCondition` method in order for
the steps to be able to identify when a managed index is part of a DataStream.

If a managed index is part of a DataStream the rollover target is the DataStream
name and the highest generation index is the write index (ie. the rolled index).

Fix assertion catching in aggregation supported type test (#56466) (#57382)
At some point, we changed the supported-type test to also catch
assertion errors.  This has the side effect of also catching the
`fail()` call inside the try-catch, which silently smothered some
failures.

This modifies the test to throw at the end of the try-catch
block to prevent from accidentally catching itself.

Catching the AssertionError is convenient because there are other locations
that do throw an assertion in tests (due to hitting an assertion
before the exception is thrown) so I think we should keep it around.

Also includes a variety of fixes to other tests which were failing
but being silently smothered.

[7.x] [ML] mark forecasts for force closed/failed jobs as failed (#57143) (#57374)
* [ML] mark forecasts for force closed/failed jobs as failed (#57143)

forecasts that are still running should be marked as failed/finished in the following scenarios:

- Job is force closed
- Job is re-assigned to another node.

Forecasts are not "resilient". Their execution does not continue after a node failure. Consequently, forecasts marked as STARTED or SCHEDULED should be flagged as failed. These forecasts can then be deleted.

Additionally, force closing a job kills the native task directly. This means that if a forecast was running, it is not allowed to complete and could still have the status of `STARTED` in the index.

This adds a max_model_memory setting to forecast requests. 
This setting can take a string value that is formatted according to byte sizes (i.e. "50mb", "150mb").

The default value is `20mb`.

There is a HARD limit at `500mb` which will throw an error if used.

If the limit is larger than 40% the anomaly job's configured model limit, the forecast limit is reduced to be strictly lower than that value. This reduction is logged and audited.

SQL: Fix unecessary evaluation for CASE/IIF (#57159) (#57262)
Previously, `CASE` and `IIF` when translated to painless scripts
(used in GROUP BY, HAVING, WHERE) a custom `caseFunction`
registered in the `InternalSqlScriptUtils` was used. This function
received and array of arbitrary length:
```[condition1, result1, condition2, result2, ... elseResult]```

Painless doesn't know of the context and therefore is evaluating
all conditions and results before invoking the `caseFunction` on them.
As a consequence, erroneous result expressions (i.e. division by 0)
where always evaluated despite of the guarding condition.

Replace the `caseFunction` with painless `<cond> ? <res1> : <res2>`
expressions to properly guard the result expressions and only evaluate
the one for which its guarding condition evaluates to true (or of course
the elseResult).

As a bonus, this approach includes performance benefits since we avoid
unnecessary evaluations of both conditions and result expressions.

Fix key usage in SamlAuthenticatorTests (#57124) (#57129)
In #51089 where SamlAuthenticatorTests were refactored, we missed
to update one test case which meant that a single key would be
used both for signing and encryption in the same run. As explained
in #51089, and due to FIPS 140 requirements, BouncyCastle FIPS
provider will block RSA keys that have been used for signing from
being used for encryption and vice versa

This commit changes testNoAttributesReturnedWhenTheyCannotBeDecrypted
to always use the specific keys we have added for encryption.

This change ensures that we stop the maintenance service on all nodes
when a data node is restarted. This ensures that we don't send

This commit also raises the log level to trace for some packages
in order to investigate the failures to acquire a shard lock
after a restart.

SQL: [Tests] Move JDBC integration tests to new module (#56872) (#57072)
Move the JDBC functionality integration tests from `:sql:qa` to a separate
module `:sql:qa:jdbc`. This way the tests are isolated from the rest of the
integration tests and they only depend to the `:sql:jdbc` module, thus
removing the danger of accidentally pulling in some dependency that may
hide bugs.

Moreover this is a preparation for #56722, so that we can run those tests
between different JDBC and ES node versions and ensure forward
compatibility.

Move the rest of existing tests inside a new `:sql:qa:server` project, so that
the `:sql:qa` becomes the parent project for both and one can run all the integration
tests by using this parent project.

Fix custom policy in plugins in FIPS 140 (#52046) (#57049)
Our FIPS 140 testing depends on setting the appropriate java policy
in order to configure the JVM in FIPS mode. Some tests (
discovery-ec2 and ccr qa ) also needed to set a custom policy file
to grant a specific permission, which overwrote the FIPS related
policy and tests would fail. This change ensures that when a
custom policy needs to be set in these tests, the permissions that
are necessary for FIPS are also set.

[ML] adds WKT support in filestructurefinder (#57014) (#57032)
Field mapping detection is done via grok patterns. 
This commit adds well-known text (WKT) formatted geometry detection.

If everything is a `POINT`, then a `geo_point` mapping is preferred. 
Otherwise, if all the fields are WKT geometries a `geo_shape` mapping is preferred.

This does **NOT** detect other types of formatted geometries (geohash, comma delimited points, etc.)

* Fix temp dir locked errors

The tests involving a temporary directory (containing the JDBC JAR) fail
on Windows because they can't be deleted, due to still being in use.
This commit forces a premature closing of the JAR file, which mitigates
the failure by giving the JVM more time to collect any open FDs.
(Calling the System.gc() in the tests is another working alternative
fix.)

The stream-based JAR access is taken care by disabling the cache usage

Alan Woodward 18bfbeda29 Move merge compatibility logic from MappedFieldType to FieldMapper (#56915)
Merging logic is currently split between FieldMapper, with its merge() method, and
MappedFieldType, which checks for merging compatibility. The compatibility checks
are called from a third class, MappingMergeValidator. This makes it difficult to reason
about what is or is not compatible in updates, and even what is in fact updateable - we
have a number of tests that check compatibility on changes in mapping configuration
that are not in fact possible.

This commit refactors the compatibility logic so that it all sits on FieldMapper, and
makes it called at merge time. It adds a new FieldMapperTestCase base class that
FieldMapper tests can extend, and moves the compatibility testing machinery from
FieldTypeTestCase to here.

[ML] relax throttling on expired data cleanup (#56711) (#56895)
Throttling nightly cleanup as much as we do has been over cautious.

Night cleanup should be more lenient in its throttling. We still
keep the same batch size, but now the requests per second scale
with the number of data nodes. If we have more than 5 data nodes,
we don't throttle at all.

Additionally, the API now has `requests_per_second` and `timeout` set.
So users calling the API directly can set the throttling.

This commit also adds a new setting `xpack.ml.nightly_maintenance_requests_per_second`.
This will allow users to adjust throttling of the nightly maintenance.

Ensure that .watcher-history-11* template is in installed prior to use (#56734)
WatcherIndexTemplateRegistry as of https://github.com/elastic/elasticsearch/pull/52962 
requires all nodes to be on 7.7.0 before it allows the version 11 index template to be 
installed.

While in a mixed cluster, nothing prevents Watcher from running on the new
host before the all of the nodes are on 7.7.0. This will result in the
.watcher-history-11* index without the proper mappings. Without the proper
mapping a single document (for a large watch) can exceed the default 1000 field
limit and cause error to show in the logs.

This commit ensures the same logic for writing to the index is applied as for
installing the template. In a mixed cluster, the `10` index template will continue
to be written. Only once all of nodes are on 7.7.0+ will the `11` index template
be installed and used.

SQL: JDBC: fix access to the Manifest for non-entry JAR URLs (#56797) (#56839)
* JDBC: fix access to the Manifest for non-entry JAR

The JDBC driver will attempt to read its version from the Manifest file
embedded into its JAR. The URL pointing to the JAR can be provided in a
few ways.

So far, accessing the Manfiest was attempted by getting a URLConnection
out of the URL and then getting an input stream out of this connection.
For file JAR URLs, this only works however if the URL points to the
driver as a JAR file entry (i.e. <sub-url>!/jdbc-driver.jar!/). If
that's not the case, the JarURLConnection will throw an IOException.

This commit fixes that: in case the URL points to a JAR entry
(jar:file:<path>/jdbc-driver.jar!/), the manifest is read directly with
JarURLConnection#getManifest().

Test adjustments for FIPS 140 (#56526)
This change aims to fix our setup in CI so that we can run 7.x in
FIPS 140 mode. The major issue that we have in 7.x and did not
have in master is that we can't use the diagnostic trust manager
in FIPS mode in Java 8 with SunJSSE in FIPS approved mode as it
explicitly disallows the wrapping of X509TrustManager.

Previous attempts like #56427 and #52211 focused on disabling the
setting in all of our tests when creating a Settings object or
on setting fips_mode.enabled accordingly (which implicitly disables
the diagnostic trust manager). The attempts weren't future proof
though as nothing would forbid someone to add new tests without
setting the necessary setting and forcing this would be very
inconvenient for any other case ( see
#56427 (comment) for the full argumentation).

This change introduces a runtime check in SSLService that overrides
the configuration value of xpack.security.ssl.diagnose.trust and
disables the diagnostic trust manager when we are running in Java 8
and the SunJSSE provider is set in FIPS mode.

[ML] Tail the C++ logging pipe before connecting other pipes (#56701)
Prior to this change the named pipes that connect the ML C++
processes to the Elasticsearch JVM were all opened before any
of them were read from or written to.

This created a problem, where if the C++ process logged more
messages between opening the log pipe and opening the last
pipe to be connected than there was space for in the named
pipe's buffer then the C++ process would block.  This would
mean it never got as far as opening the last named pipe, so
the JVM would never get as far as reading from the log pipe,
hence a deadlock.

This change alters the connection order so that the JVM
starts reading from the logging pipe immediately after opening
it so that if the C++ process logs messages while opening the
other named pipes they are captured in a timely manner and
there is no danger of a deadlock.

David Turner c10b4ae15a Support cloning of searchable snapshot indices (#56595)
Today you can convert a searchable snapshot index back into a regular index by
restoring the underlying snapshot, but this is somewhat wasteful if the shards
are already in cache since it copies the whole index from the repository again.

Instead, we can make use of the locally-cached data by using the clone API to
copy the contents of the cache into the layout expected by a regular shard.
This commit marks the searchable snapshot's private index settings as
`NotCopyableOnResize` so that they are removed by resize operations such as
cloning.

Cloning a regular index typically hard-links the underlying files rather than
copying them, but this is tricky to support in the case of a searchable
snapshot so this commit takes the simpler approach of always copying the
underlying files.

[7.x] Watcher dont add watches post index if stopped (#56556) (#56629)
Watcher adds watches to the trigger service on the postIndex action
for the .watches index. This has the (intentional) side effect of also
adding the watches to the stats. The tests rely on these stats for their
assertions. The tests also start and stop Watcher between each test for
a clean slate.

When Watcher executes it updates the .watches index and upon this update
it will go through the postIndex method and end up added that watch to the
trigger service (and stats). Functionally this is not a problem, if Watcher
is stopping or stopped since Watcher is also paused and will not execute
the watch. However, with specific timing and expectations of a clean slate
can cause issues the test assertions against the stats.

This commit ensures that the postIndex action only adds to the trigger service
if the Watcher state is not stopping or stopped. When started back up it will

Save Bounds Checks in BytesReference (#56577) (#56621)
Two spots that allow for some optimization:

* We are often creating a composite reference of just a single item in
the transport layer => special cased via static constructor to make sure we never do that
   * Also removed the pointless case of an empty composite bytes ref
* `ByteBufferReference` is practically always created from a heap buffer these days so there
is no point of dealing with all the bounds checks and extra references to sliced buffers from that
and we can just use the underlying array directly

Backport: auto create data streams using index templates v2 (#56596)
Backport: #55377

This commit adds the ability to auto create data streams using index templates v2.
Index templates (v2) now have a data_steam field that includes a timestamp field,
if provided and index name matches with that template then a data stream
(plus first backing index) is auto created.

SQL: Fix serialization of JDBC prep statement date/time params (#56492) (#56579)
The Date/Time related query params of a JDBC prepared statement
serialized using java.util.Date. The rules for serializing
`java.util.Date` objects though reside in
`XContentElasticsearchExtension` which is not available in the
jdbc jar as this class is in `server` module. Therefore, a
custom extension of the `XContentBuilderExtension` iface has been
added to the jdbc module/jar.

Moreover the sql's `qa` project had as dependency the `sql-action`
module which depends on `server` so the `XContentBuilderExtension`
was available for the integ tests hiding the real problem.

Previously, when a user was setting a `java.sql.Time` to the prepStmt,
the DataType used was `DATETIME` instead of `TIME` and therefore
prevented from filtering with a `TIME` casted field:
```
SELECT * FROM test WHERE date::TIME = ?
```

Save memory when numeric terms agg is not top (#55873) (#56454)
Right now all implementations of the `terms` agg allocate a new
`Aggregator` per bucket. This uses a bunch of memory. Exactly how much
isn't clear but each `Aggregator` ends up making its own objects to read
doc values which have non-trivial buffers. And it forces all of it
sub-aggregations to do the same. We allocate a new `Aggregator` per
bucket for two reasons:

1. We didn't have an appropriate data structure to track the
   sub-ordinals of each parent bucket.
2. You can only make a single call to `runDeferredCollections(long...)`
   per `Aggregator` which was the only way to delay collection of
   sub-aggregations.

This change switches the method that builds aggregation results from
building them one at a time to building all of the results for the
entire aggregator at the same time.

It also adds a fairly simplistic data structure to track the sub-ordinals
for `long`-keyed buckets.

It uses both of those to power numeric `terms` aggregations and removes
the per-bucket allocation of their `Aggregator`. This fairly
substantially reduces memory consumption of numeric `terms` aggregations
that are not the "top level", especially when those aggregations contain
many sub-aggregations. It also is a pretty big speed up, especially when
the aggregation is under a non-selective aggregation like
the `date_histogram`.

I picked numeric `terms` aggregations because those have the simplest
implementation. At least, I could kind of fit it in my head. And I
haven't fully understood the "bytes"-based terms aggregations, but I
imagine I'll be able to make similar optimizations to them in follow up
changes.

Serialize Monitoring Bulk Request Compressed (#56410) (#56442)
Even with changes from #48854 we're still seeing significant (as in tens and hundreds of MB)
buffer usage for bulk exports in some cases which destabilizes master nodes.
Since we need to know the serialized length of the bulk body we can't do the serialization
in a streaming manner. (also it's not easily doable with the HTTP client API we're using anyway).
=> let's at least serialize on heap in compressed form and decompress as we're streaming to the
HTTP connection. For small requests this adds negligible overhead but for large requests this reduces
the size of the payload field by about an order of magnitude (empirically determined) which is a massive reduction in size when considering O(100MB) bulk requests.

Use snapshot information to build searchable snapshot store MetadataSnapshot (#56289) (#56403)
While investigating possible optimizations to speed up searchable
snapshots shard restores, we noticed that Elasticsearch builds the
list of shard files on local disk in order to compare it with the list of
files contained in the snapshot to restore. This list of files is
materialized with a MetadataSnapshot object whose construction
involves to read the footer checksum of every files of the shard
using Store.checksumFromLuceneFile() method.

Further investigation shows that a MetadataSnapshot object is
also created for other types of operations like building the list of
files to recover in a peer recovery (and primary shard relocation)
or in order to assign a shard to a node. These operations use the
Store.getMetadata(IndexCommit) method to build the list of files
and checksums.

In the case of searchable snapshots building the MetadataSnapshot
object can potentially trigger cache misses, which in turn can
cause the download and the writing in cache of the last range of
the file in order to check the 16 bytes footer. This in turn can
cause more evictions.

Since searchable snapshots already contains the footer information
of every file in BlobStoreIndexShardSnapshot it can directly read the
checksum from it and avoid to use the cache at all to create a
MetadataSnapshot for the operations mentioned above.

This commit adds a shortcut to the
SearchableSnapshotDirectory.openInput() method - similarly to what
already exists for segment infos - so that it creates a specific
IndexInput for checksum reading operation.

Optimize date_histograms across daylight savings time (backport of #55559) (#56334)
Rounding dates on a shard that contains a daylight savings time transition
is currently something like 1400% slower than when a shard contains dates
only on one side of the DST transition. And it makes a ton of short lived
garbage. This replaces that implementation with one that benchmarks to
having around 30% overhead instead of the 1400%. And it doesn't generate
any garbage per search hit.

Some background:
There are two ways to round in ES:
* Round to the nearest time unit (Day/Hour/Week/Month/etc)
* Round to the nearest time *interval* (3 days/2 weeks/etc)

I'm only optimizing the first one in this change and plan to do the second
in a follow up. It turns out that rounding to the nearest unit really *is*
two problems: when the unit rounds to midnight (day/week/month/year) and
when it doesn't (hour/minute/second). Rounding to midnight is consistently
about 25% faster and rounding to individual hour or minutes.

This optimization relies on being able to *usually* figure out what the
minimum and maximum dates are on the shard. This is similar to an existing
optimization where we rewrite time zones that aren't fixed
(think America/New_York and its daylight savings time transitions) into
fixed time zones so long as there isn't a daylight savings time transition
on the shard (UTC-5 or UTC-4 for America/New_York). Once I implement
time interval rounding the time zone rewriting optimization *should* no
longer be needed.

This optimization doesn't come into play for `composite` or
`auto_date_histogram` aggs because neither have been migrated to the new
`DATE` `ValuesSourceType` which is where that range lookup happens. When
they are they will be able to pick up the optimization without much work.
I expect this to be substantial for `auto_date_histogram` but less so for
`composite` because it deals with fewer values.

Note: My 30% overhead figure comes from small numbers of daylight savings
time transitions. That overhead gets higher when there are more
transitions in logarithmic fashion. When there are two thousand years
worth of transitions my algorithm ends up being 250% slower than rounding
without a time zone, but java time is 47000% slower at that point,
allocating memory as fast as it possibly can.

Simplify signature of FieldMapper#parseCreateField. (#56144)
`FieldMapper#parseCreateField` accepts the parse context, plus a list of fields

This commit simplifies the signature by removing the list of fields, and having
the mappers add the fields directly to `ParseContext#doc()`. I think this is
nicer for implementors, because previously fields could be added either through
the list, or the context (through `add`, `addWithKey`, etc.)

SQL: introduce a query builder for the Rest tests (#55094) (#56221)
* Introduce a query builder for the rest tests

The new BaseRestSqlTestCase.RequestObjectBuilder class is a helper class
to build REST request objects for the tests. Consequently, "manual" string
concatenation to form JSON is done away with.

The class mimics SqlQueryRequestBuilder API.

Add geo_shape support for geotile_grid and geohash_grid (#55966) (#56228)
this commit adds aggregation support for the geo_shape field
type on geo*_grid aggregations.

it introduces a Tiler for both tiles and hashes that enables a new type of
ValuesSource to replace the GeoPoint's CellIdSource. This makes it possible
for the existing Aggregator to be re-used, so no new implementations of
the grid aggregators are added.

[Transform] fixes http status code when bad scripts are provided (#56117) (#56219)
Transforms should propagate up the search execution exception if one is returned when it does the test query.

[7.x][ML] More advanced model snapshot retention options (#56194)
This PR implements the following changes to make ML model snapshot
retention more flexible in advance of adding a UI for the feature in
an upcoming release.

- The default for `model_snapshot_retention_days` for new jobs is now
  10 instead of 1
- There is a new job setting, `daily_model_snapshot_retention_after_days`,
  that defaults to 1 for new jobs and `model_snapshot_retention_days`
  for pre-7.8 jobs
- For days that are older than `model_snapshot_retention_days`, all
  model snapshots are deleted as before
- For days that are in between `daily_model_snapshot_retention_after_days`
  and `model_snapshot_retention_days` all but the first model snapshot
  for that day are deleted
- The `retain` setting of model snapshots is still respected to allow
  selected model snapshots to be retained indefinitely

SQL: Fix DATETIME_PARSE behaviour regarding timezones (#56158) (#56182)
Previously, when the timezone was missing from the datetime string
and the pattern, UTC was used, instead of the session defined timezone.
Moreover, if a timezone was included in the datetime string and the
pattern then this timezone was used. To have a consistent behaviour
the resulting datetime will always be converted to the session defined
timezone, e.g.:
```
SELECT DATETIME_PARSE('2020-05-04 10:20:30.123 +02:00', 'HH:mm:ss dd/MM/uuuu VV') AS datetime;
```
with `time_zone` set to `-03:00` will result in

Use workers to warm cache parts (#55793) (#56181)
Today the cache prewarming introduced in #55322 works by 
enqueuing altogether the files parts to warm in the 
searchable_snapshots thread pool. In order to make this fairer
 among concurrent warmings, this commit starts workers that 
concurrently polls file parts to warm from a queue, warms the 
part and then immediately schedule another warming 
execution. This should leave more room for concurrent 
shard warming to sneak in and be executed.

SQL: Fix issue with date range queries and timezone (#56115) (#56174)
Previously, the timezone parameter was not passed to the RangeQuery
and as a results queries that use the ES date math notation (now,
now-1d, now/d, now/h, now+2h, etc.) were using the UTC timezone and
not the one passed through the "timezone"/"time_zone" JDBC/REST params.
As a consequence, the date math defined dates were always considered in
UTC and possibly led to incorrect results for queries like:
```
SELECT * FROM t WHERE date BETWEEN now-1d/d AND now/d
```

[7.x][ML] Fix race condition updating reindexing progress (#56135) (#56146)
In #55763 I thought I could remove the flag that marks
reindexing was finished on a data frame analytics task.
However, that exposed a race condition. It is possible that
between updating reindexing progress to 100 because we
have called `DataFrameAnalyticsManager.startAnalytics()` and
a call to the _stats API which updates reindexing progress via the
method `DataFrameAnalyticsTask.updateReindexTaskProgress()` we
end up overwriting the 100 with a lower progress value.

This commit fixes this issue by bringing back the help of
a `isReindexingFinished` flag as it was prior to #55763.

Let realms gracefully terminate the authN chain (#55623)
AuthN realms are ordered as a chain so that the credentials of a given
user are verified in succession. Upon the first successful verification,
the user is authenticated. Realms do however have the option to cut short
this iterative process, when the credentials don't verify and the user
cannot exist in any other realm. This mechanism is currently used by
the Reserved and the Kerberos realm.

This commit improves the early termination operation by allowing
realms to gracefully terminate authentication, as if the chain has been
tried out completely. Previously, early termination resulted in an
authentication error which varies the response body compared
to the failed authentication outcome where no realm could verify the
credentials successfully.

Reserved users are hence denied authentication in exactly the same
way as other users are when no realm can validate their credentials.

[7.x] Delay warning about missing x-pack (#56142)
* Delay warning about missing x-pack (#54265)

Currently, when monitoring is enabled in a freshly-installed cluster,
the non-master nodes log a warning message indicating that master may
not have x-pack installed. The message is often printed even when the
master does have x-pack installed but takes some time to setup the local
exporter for monitoring. This commit adds the local exporter setting
`wait_master.timeout` which defaults to 30 seconds. The setting
configures the time that the non-master nodes should wait for master to
setup monitoring. After the time elapses, they log a message to the user
about possible missing x-pack installation on master.

The logging of this warning was moved from `resolveBulk()` to
`openBulk()` since `resolveBulk()` is called only on cluster updates and
the message might not be logged until a new cluster update occurs.

[ML] reduce InferenceProcessor.Factory log spam by not parsing pipelines (#56020) (#56126)
If there are ill-formed pipelines, or other pipelines are not ready to be parsed, `InferenceProcessor.Factory::accept(ClusterState)` logs warnings. This can be confusing and cause log spam.

It might lead folks to think there an issue with the inference processor. Also, they would see logs for the inference processor even though they might not be using the inference processor. Leading to more confusion.

Additionally, pipelines might not be parseable in this method as some processors require the new cluster state metadata before construction (e.g. `enrich` requires cluster metadata to be set before creating the processor).

Add auto create action (#56122)
Backport of #55858 to 7.x branch.

Currently the TransportBulkAction detects whether an index is missing and
then decides whether it should be auto created. The coordination of the
index creation also happens in the TransportBulkAction on the coordinating node.

This change adds a new transport action that the TransportBulkAction delegates to
if missing indices need to be created. The reasons for this change:

* Auto creation of data streams can't occur on the coordinating node.
Based on the index template (v2) either a regular index or a data stream should be created.
However if the coordinating node is slow in processing cluster state updates then it may be
unaware of the existence of certain index templates, which then can load to the
TransportBulkAction creating an index instead of a data stream. Therefor the coordination of
creating an index or data stream should occur on the master node. See #55377

* From a security perspective it is useful to know whether index creation originates from the
create index api or from auto creating a new index via the bulk or index api. For example
a user would be allowed to auto create an index, but not to use the create index api. The
auto create action will allow security to distinguish these two different patterns of
index creation.
This change adds the following new transport actions:

AutoCreateAction, the TransportBulkAction redirects to this action and this action will actually create the index (instead of the TransportCreateIndexAction). Later via #55377, can improve the AutoCreateAction to also determine whether an index or data stream should be created.

The create_index index privilege is also modified, so that if this permission is granted then a user is also allowed to auto create indices. This change does not yet add an auto_create index privilege. A future change can introduce this new index privilege or modify an existing index / write index privilege.
